The specific embodiment
As shown in Figure 1, the utility model is achieved like this, it comprises evaporimeter 1, expansion valve 2, vapour liquid separator 3, device for drying and filtering 4, liquid-sighting glass 5, compressor 6, reservoir pressure control valve 7, condensing pressure by-passing valve 8, reservoir 9, condensation pressure regulation valve 10, check valve 11, air-cooled condenser 12, condensation fan 13, it is characterized in that compressor 6 connects condensation pressure regulation valve 10, condensation pressure regulation valve 10 connects air-cooled condenser 12, air-cooled condenser 12 connects check valve 11, check valve 11 connects reservoir 9, reservoir pressure control valve 7 and condensing pressure by-passing valve 8 also are connected in 9 of compressor 6 and reservoirs in parallel, reservoir 9 connects liquid-sighting glass 5, liquid-sighting glass 5 connects device for drying and filtering 4, device for drying and filtering 4 connects expansion valve 2, expansion valve 2 connects evaporimeter 1, evaporimeter 1 connects vapour liquid separator 3, vapour liquid separator 3 connects compressor 6, and air-cooled condenser 12 next doors are connected with condensation fan 13, and condensing pressure by-passing valve 8 connects reservoir pressure control valve 7.Difference minimum condensing pressure of initialization system and minimum reservoir pressure on condensation pressure regulation valve 10 and reservoir pressure control valve 7.
When the environment temperature height, when system condensing pressure is higher than setting pressure, condensation pressure regulation valve 10 standard-sized sheets, condensing pressure by-passing valve 8 and reservoir pressure control valve 7 complete shut-downs.Cold-producing medium compresses the refrigerant gas that becomes HTHP and is discharged from compressor 6 after, enter air-cooled condenser 12 by condensation pressure regulation valve 10, in air-cooled condenser 12, be condensed into liquid refrigerant, through check valve 11 enter again reservoir 9, after through liquid-sighting glass 5, device for drying and filtering 4, expansion valve 2, after through expansion valve 2 throttlings, enter evaporimeter 1 absorption heat, be evaporated to the gaseous refrigerant of low-temp low-pressure after behind the vapour liquid separator 3, sucked compressor 6 once more, so circulation.
When environment temperature is reduced to system condensing pressure when being lower than setting pressure gradually, condensation pressure regulation valve 10 apertures reduce gradually, after cold-producing medium compresses in compressor 6 and discharges, a part enters air-cooled condenser 12 by condensation pressure regulation valve 10, in air-cooled condenser 12, be condensed into liquid refrigerant, enter reservoir 9 again through check valve 11; Another part then enters reservoir 9 by condensing pressure by-passing valve 8 bypasses and reservoir control valve 7 bypasses, at this moment, reservoir pressure control valve 7 compares according to the setting pressure of reservoir pressure with self, regulate the aperture of reservoir pressure control valve 7, equiulbrium flow is crossed the cold-producing medium on condensing pressure by-passing valve bypass and reservoir pressure by pass around regulator road, makes reservoir pressure be stabilized on the setting pressure.After cold-producing medium enters reservoir 9, pass through liquid-sighting glass 5, device for drying and filtering 4 again after after 2 throttlings of overexpansion valve, enter evaporimeter 1 and absorb heat, the gaseous refrigerant that is evaporated to low-temp low-pressure is after behind the vapour liquid separator 3, sucked compressor 6 once more, so circulation.
